Why it works: Milk and lemon are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Make the base
Soak the isinglass in 1 quart of water for 2 hours or overnight, weighted down.
Pour 1 pint of boiling water over the soaked isinglass, then add the sugar and lemon juice.
Chill the mixture on ice until it begins to thicken.
Whip and set
Beat the egg whites to stiff peaks and fold them into the mixture.
Pour the mixture into a vessel rinsed with cold water and place it on ice.
Serve
Serve with a custard made from the 4 yolks, 1 egg, and the milk.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the mixture as it chills, giving it a light, firm body.
- Egg whites
- Whipped to stiff peaks, they trap air and make the dessert light and airy.
- Sugar
- Adds sweetness and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity and brightness that cut through the sweetness.
- Egg yolks
- Thicken the custard and add richness.
- Milk
- Forms the liquid base of the custard, adding moisture and creaminess.
The step that matters
Fold the whipped egg whites in gently. Stiff egg white foam holds air that gives the dessert its lightness. Stirring or folding too hard deflates the foam, so the mixture turns dense instead of airy.

Fit is the average pairing score against milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
